BOILER-CLEAN ER.

SPECIFICATION forming part of Letters Patent No. 496,318, dated April25, 1893. Application filed July 14, 1892-: Serial No. 440,024. (Nomodel.)

To all whom it may concern:

Be it known that I, JOSEPH A. MALONEY, a citizen of the United States,residing at Leavenworth, in the county of Leavenworth and State ofKansas, have invented certainnew and useful Improvements inBoiler-Cleaners; and I do hereby declare the following to be a full,clear, and exact description of the in vention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

My invention has relation to improvements in filters or. devices forremoving sediment and scale from water in steam boilers when inoperation, and it has for its general object to provide a thoroughlyefficient device of a cheap and compact construction adapted to beplaced within a boiler.

WVith the foregoing end in view, the novelty of the invention will befully understood from the following description and claims when taken inconjunction with the annexed drawings, in which:

Figure 1,is a vertical longitudinal, diametrical section of a steamboiler with my improved filter in position therein. Fig. 2, is anenlarged side elevation of the filter removed. Fig. 3, isaperspectiveview of the filter frame removed. Fig. 4, is a plan view of the filterbody with the frame and cover removed. Fig. 5, is an enlarged transversesection taken in the plane indicated by the line at, at, of Fig. 2, withthe filter frame and cover in position, and Fig. 6, is a vertical,longitudinal central section of a modified construction.

Referring by letter to the said drawings and more particularly to Figs.1, to 5, inclusive: A, indicates a steam boiler which may be of theordinary or any approved construction, and B, indicates the hot airfines of the same.

0, indicates the settling chamber of my improved filter which ispreferably of a general rectangular form as shown and is designed torest within the boiler beneath the fines B, thereof, and adjacent to thelower manhole as shown in Fig. 1, of the drawings. The side walls a, ofthe chamber 0, are preferably formed integral with the bottom 1), as arealso the end walls 0; and these end walls 0, the rearward one of whichis of a less height than the walls a, are provided with the inwardlybent flan es d which are riveted or otherwise connected to the sidewalls a, and are bent over a form or the like so as to aiford thepockets '6. These pockets e, are preferably of a' semi-circular form incross-section as shown and they are designed to receive cotton-waste,asbestus or other packing, whereby it will be seen that a thoroughlytight joint will be effected between the side and end walls.

D, indicates the transverse partitions of the settling chamber which arearranged at suitable intervals in the length thereof and are designed todivide the same into several compartments adapted to receive thesediment,-

scale, &o. These partitions D, which are preferably of the proportionalheight illustrated, maybe connected to the side and bottom walls of thechamber in any approved manner and they are preferably braced by themetal straps E, which are connected to their upper edges and areprovided at their ends with the downwardly disposed angular branches 6',designed to be riveted or otherwise connected to the side walls a. Thusit will be readily perceived that the partitions will be fixedly held inposition.

Mounted in longitudinal ways or grooves upon the inside of the sideWalls a, adjacent to the upper edges thereof, is the removable cover F,which is provided adjacent to its forward end with an aperture T, whichis preferably of an oval form and is designed to receive the preferablyoval tube g, of the receiver G. This receiver G, which is angularlydisposed with respect to the tube g, as shown, is of a general funnelshape and is designed to rest above the fiues B, with its lower sidesubmerged so that it will skim the water and receive the sediment andscale which are raised to the surface of the water by the circulation ofthe same incidental to the boiling process.

Suitably connected to the cover F, by rivets or the like is a packingcap H, which is provided with a central ap'erture h, for the passage ofthe tube g, and with a depending skirt 2', of felt or the like whichlatter impinges against the tube 9, and is designed to insure a tightjoint of the same to the cover.

As better illustrated in Fig. 5, of the drawings a sufficient space isalforded between the upper edges of the partitions D, and the cover F,to receive the filtering frame J, which is preferably formed ofangleiron and is of such a) sizg that it will take loosely into thecham- Connected to the vertically disposed branches of the frame .I, isthe filter strip or strips M, of felt or other suitable material, whichstrip is bent inwardly by the cover when the same is placed in position,whereby it will be seen that a chamber will be formed between thefiltering strip and the walls and cover of the chamber O entirely aroundthe upper part of said chamber, the inwardly bent edges of the filteringstrip forming a substantially tight joint, by reason of which thepassage of the water will be retarded and the sediment and scale will beallowed to settle in the compartments formed by the partitions D.

In operation the water in the boiler takes into the receiver G, andpasses through the tube (,into the forward compartment of the settlingchamber from whence it passes successively through the severalcompartments and back again into the boiler through the opening formedbetween the rear end wall 0, and the cover F. It will be perceivedthatin order for the water to pass through the sediment chamber into theboiler, it will have to pass through the filtering strip M, by means ofwhich it will be thoroughly filtered from all sedimentary substances.

P indicates a blow off cock for cleaning the filter.

In Fig. 6, of the drawings I have illustrated a settling chamber C,which is similar to the chamber 0, before described, with the exceptionthat it does not embody a filtering frame, and has its partition wallsI), inclined instead of perpendicular as illustrated in Figs. 1 to 5.

Although I have in some respects, specifically described theconstruction and relative arrangement of the several elements of myimproved device, I do not desire to be confined to the same, as suchchanges or modifications may be made as fairly fall within the scope ofmy invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a filter or device for removing sediment, scale, 850., from thewater in boilers, the settling chamber described, comprising the bottom,the side walls, and the end walls having the inwardly bent flangesconnected to the side walls and bent to form pockets adapted to receivecotton-waste, asbestus or other packing substantially as and for thepurpose set forth.

2. In a filter or device for removing sediment, scale, &c., from thewater in boilers, the combination with the settling chamber having aseries of transverse partition walls and the cover of the filter framelocated in the upper part of the chamber, and having a strip or stripsof felt or equivalent material substantially as and for the purpose setforth.

3. In a filter or device for removing sediment, scale, &c., from thewater in boilers, the combination with the settling chamber, and thetube connecting the settling chamber and the receiver; of the packingcap connected to the settling chamber and having an aperture for thepassage of the connecting tube, and a skirt of felt or equivalentmaterial connected to the packing cap and impinging upon the connectingtube, substantially as and for the purpose specified.

In testimony whereof I affix my sign aturc in presence of two witnesses.
